6303-ZZ Shielded Ball Bearings

6303-ZZ are small ball bearings with metal seals and grease on both sides, suitable for high radial loads and light axial loads in both directions, providing high running accuracy, quietness and high speed.

Ball-bearing inner dimension 17mm X outer dimension 47mm X width 14mm, suitable for all kinds of power tools, garden tools, roller skating products, etc.

6202-2RS single row deep groove ball bearing has the highest speed rating of all bearing types. Due to the spherical shape of the balls, only the tops of the balls run on the raceway.

Since it has a point contact with the raceway, unlike the line contact in a roller bearing, lower friction and higher-rated speeds can be achieved.
